The lung anatomy model is a commonly used auxiliary tool for medical teaching and research, mainly used to display the structural characteristics and anatomical relationships of the human lungs. The model is usually designed based on the scale of a real person, clearly showing the shape of the left and right lungs, the distribution of lung lobes and the interlobar fissures. The left lung has two lobes and the right lung has three lobes. The overall form is intuitive and realistic. Some models further subdivide the lung segments and distinguish them with different colors to help learners quickly understand the branching pattern of "lung lobe - lung segment - bronchus" and establish a clear spatial concept.

In terms of internal structure, lung anatomy models are often equipped with the branching directions of the tracheal and bronchial trees, and some can even display the enlarged structures of the bronchioles and alveoli, enabling learners to intuitively understand the microscopic processes of gas exchange. Meanwhile, the distribution of the pulmonary artery and pulmonary vein can also be presented in the model, which is convenient for grasping the characteristics of the pulmonary circulation and its connection with the systemic circulation.

This model is of great significance in medical teaching. It not only helps students master anatomical knowledge intuitively but also demonstrates the lesion distribution of common lung diseases in pathology and clinical teaching, such as pneumonia, tuberculosis and lung cancer. It provides medical staff with a visual and reusable learning platform, and also has positive value in improving the efficiency of surgical training, health education and doctor-patient communication.
